Summary: This study evaluated the use of inert feed enriched with Lb. paracasei subsp. paracasei BGHN14 as a weaning diet for first feeding pike-perch larvae. The results showed that weaning with BGHN14 homogenate coated microdiet supports skeleton development and improves fish growth in comparison to other feeding methods.

Summary: Glycerophospholipids are major components of cell membranes with diverse fatty acyl chain compositions and polar head groups. Phospholipase A(2) enzymes play a critical role in metabolism by hydrolyzing glycerophospholipids, and different human PLA(2) enzymes show distinct preferences for sn-1 acyl chain linkages.

Summary: Phospholipase A2 (PLA2) is a group of enzymes that release fatty acids and lysophospholipids from glycerophospholipids. They have been implicated in signal transduction, membrane homeostasis, energy production, and lipid pathway regulation. Perturbation of PLA2-driven lipid pathways may be associated with various diseases. This review discusses the physiological functions of the PLA2 superfamily, focusing on different PLA2 families and their roles in lipid metabolism.

Summary: This study investigates the effects of dietary soybean lecithin (SL) inclusion on the growth performance, liver metabolism, resistance to hypoxia stress, and potential molecular mechanisms in rock bream larvae. The results show that dietary SL inclusion promotes growth performance, survival rate, stress resistance, and improves intestinal structure. Additionally, a high SL inclusion diet increases the activity of lipolysis-related enzymes in liver tissue but decreases the activity of amino acid catabolism-related enzymes.

Summary: The study showed that reducing TI activity in SPC from soymilk to <= 21 TIU/mg sample (<= 9.66 TIU/mg diet) allowed replacement of 80% of FM protein without affecting growth performance and health status. Additionally, a significant decrease in phosphorus discharge suggests ecological benefits through improving diet utility by lowering TI activity in SPCs from soymilk.

Summary: This study aimed to determine the effects of rotifer DHA and taurine on larval tissue levels, prey hunting success, growth performance, and retinal opsin gene expression in developing gilthead sea bream larvae. It was found that rotifer DHA significantly influenced prey consumption and promoted growth, while taurine primarily affected nutrient assimilation and growth enhancement. Additionally, both DHA and taurine had significant effects on opsin gene expression, with DHA having a stronger influence on cone and rod opsin genes in younger larvae, and taurine being more dominant in regulating gene expression in older fish.

Summary: The study found that the bloom of P. obtusidens occurred in a phosphate replete environment, unlike previous studies, suggesting that APA was regulated by internal P growth demand rather than external P availability. Very high APA was observed during the early-bloom phase, followed by a significant decrease at the peak of the bloom.

Summary: This study investigates the effects of PhoD-type alkaline phosphatase (AP) mutation on lipid composition and metabolic regulation in the diatom Phaeodactylum tricornutum. The mutation leads to modified lipid composition, increased production of fatty acids, lysophosphatidylcholine, lysophosphatidylethanolamine, ceramide, phosphatidylinositol bisphosphate, and monogalactosylmonoacylglycerol, and upregulation of genes involved in fatty acid biosynthesis. The mutant also exhibits increased content of omega-3 long-chain polyunsaturated fatty acid (LC-PUFA)-bound phospholipids, suggesting that AP mutation could improve the bioavailability of LC-PUFAs.

Summary: The study proposes a novel protocol for immobilization and stabilization of Lecitase Ultra (R) by fixing bimolecular aggregates onto support surfaces, resulting in significantly increased stability compared to diluted enzyme solutions. The most stable derivative was obtained through covalent immobilization, showing a 300-fold increase in stability compared to diluted enzyme and 75-fold increase compared to open Lecitase adsorbed onto hydrophobic supports. The bimolecular aggregate adsorbed onto polyethyleneimine-agarose exhibited the best combination of activity and stability for hydrolysis of krill oil. Omega-3 acids in the krill oil at the sn-2 position are released by phospholipase A1 due to migration issues.

Summary: Blood-brain barrier (BBB) impairment is related to the development of Alzheimer's disease (AD), and aging plays a role in the decrease of ligand-specific receptor-mediated transcytosis (RMT) and the increase of non-specific caveolar transcytosis in brain endothelial cells (BECs), leading to neurotoxic protein entry and reduced therapeutic index in central nervous system drug delivery.

Summary: The previously unknown ability of 2-(germatran-1-yloxy)ethylamine to affect the activity of alkaline phospholipase A(2) was studied, showing inhibition of the enzyme activity. This may have implications for correcting lipid metabolism and developing new pharmacological agents for prevention and suppression of hyperlipidemias.

Summary: The golden grey mullet (Liza aurata) has potential for sustainable aquaculture expansion, but the lack of sustainable juvenile provision is a major bottleneck. This study aimed to describe the reproductive management of Liza aurata broodstock and explore the reproductive lipid metabolism of the species. The results showed successful natural spawning under controlled conditions and highlighted the importance of highly unsaturated fatty acids for gonadal development. These findings can contribute to improving broodstock management and feed formulation for sustainable aquaculture growth.

Summary: This study investigated the effects of dietary copper (Cu) levels on the growth, oxidative stress, fatty acid profile, and bone health of gilthead seabream larvae. The results showed that larval growth and survival were not affected by different dietary Cu levels. However, Cu deficiency symptoms, such as increased lipid peroxidation and reduced bone mineralization, were observed in larvae fed a non-supplemented diet. On the other hand, dietary Cu supplementation improved fatty acid composition and reduced anomalies in seabream larvae.

Summary: This study assessed the relationship between morphology and metabolism during the development of Chelon auratus. The results showed that ETS activity is linked to individual morphology, particularly body size and posterior area. Fish body shape is a key factor influencing various traits such as swimming, foraging, mating, migrations, and predator avoidance.

Summary: This 12-day experiment investigated the effects of enriching Artemia with experimental microalgal emulsions on Penaeus vannamei postlarvae. The results showed that enriching Artemia with experimental microalgal emulsions significantly increased the content of three essential fatty acids in the postlarvae and improved the health of their hepatopancreas.

Summary: Substantial progress has been made in improving aquaculture feeds and feeding technologies over the past 20 years. The feed conversion efficiency and ingredient sustainability have improved significantly. However, there is still a need to define the requirements, especially for species farmed in the developing world. Precision nutrition approach and diversification of ingredient options are essential for sustainable aquaculture. The use of automated feeding systems is increasing in advanced aquaculture systems, while manual labor is still prevalent in the developing world.

Summary: Sustainable aquaculture expansion is crucial for global food security. This study evaluated different co-feeding protocols for larval rearing of flathead grey mullet, a promising species for aquaculture diversification. The results suggest that maintaining rotifers as live feed until 30-32 days post-hatching and introducing Artemia sp. from 26-29 days post-hatching can maximize survival and improve growth of the larvae.

Summary: Despite limited research, this study found that vitamin K is important for growth and bone health in gilthead seabream larvae. Feeding larvae with 4.98 mg kg(-1) of vitamin K-3 resulted in the highest growth, while higher levels of vitamin K-3 reduced growth and survival. The incidence of bone anomalies decreased as the level of vitamin K-3 increased, with the optimal level being 5 mg kg(-1). However, high levels of vitamin K-3 (22.9 and 58.51 mg kg(-1)) caused deformities, reduced mineralization, and imbalances in bone health-related gene expression.
